Iowa linebacker Jay Higgins says there is a sense of urgency as the Hawkeyes get ready for the upcoming season. Higgins is one of several Hawkeyes who returned for an additional year after a 10-4 record that included a Big Ten west division title.

Higgins says an experienced defense has high expectations.

Higgins led the nation in tackles last season and credits the design of the Iowa defense.

Higgins says the defense line helps keep the linebackers clean to make tackles.

Higgins believes the defense will be helped by an improved offense under new coordinator Tim Lester.

Higgins made his comments at Big Ten Media Days in Indianapolis.
